关于ProGuard for Android的新文档说,要在项目主目录的default.properties文件中添加一行.但是,在打开此文件时,我在顶部阅读:

# This file is automatically generated by Android Tools. 
# Do not modify this file -- YOUR CHANGES WILL BE ERASED! 

我错过了什么吗？

另外,有没有办法让ProGuard仅用于Eclipse的生产构建(即,在导出成品时)？

我配置了:

-keep ,allowoptimization,allowobfuscation,allowshrinking public class     org.jf.dexlib2.dexbacked.** {
    *;
}

但仍然收到警告:

 Note: the configuration keeps the entry point 'com.trusteer.trf.dex_parser { int get_strings_count(org.jf.dexlib2.dexbacked.DexBackedDexFile); }', but not the descriptor class 'org.jf.dexlib2.dexbacked.DexBackedDexFile'

我使用的是proguard 4.7版(在Android SDK中)

我该怎么办？

我在这里的时间很短,所以我真的希望这里有人知道如何解决这些问题:

[proguard] Warning: android.support.v4.view.ViewConfigurationCompatFroyo: can't find referenced method 'int getScaledPagingTouchSlop()' in class android.view.ViewConfiguration

我试图通过将以下内容添加到文件〜/ .bashrc来扩展我的$ PATH变量在git bash(MinGW shell)中

PATH=$PATH':/c/Program Files/maven/apache-maven-3.2.5/bin'

在我这样做并重新启动bash后,似乎$ PATH变量被扩展为预期:

$ echo $PATH
MANY_OTHER_PATHS:/c/Program Files/maven/apache-maven-3.2.5/bin

但我仍然无法在给定目录中执行程序:

$ mvn
bash: mvn: command not found

这里出了什么问题？如何正确扩展PATH变量？

我试图在我的Android应用程序上运行Proguard并遇到问题.

我正在使用SpongyCastle jar(复制和过去的完整充气城堡与包重命名,所以它不与版本中建立的机器人充气城堡冲突)

运行proguard时,我看到以下内容

我该如何解决？将rt.jar添加到我的库中？

proguard的重点是缩小代码,但我不断添加jar来解决这些问题,其中proguard抱怨它无法找到一个类!我错过了什么吗？

我是Spring Boot的新手，尝试使用spring初始值设定项在intellij中构建我的第一个Spring Boot项目（Maven）时，在创建项目后运行项目时出现此错误：

无法访问org.springframework.context.ConfigurableApplicationContext的org.springframework.context.ConfigurableApplicationContext类文件

我遵循了许多教程，但是每次遇到此错误时，如何解决此问题？

考虑这个proguard语句:

-keep public class * extends android.support.design.widget.CoordinatorLayout$Behavior { *; }

在这个声明中添加{*; } 意思？

它保留所有方法吗？所有领域？还是整个班级？

我正在使用Apache Commons 1.4.1库来压缩和解压缩".tar.gz"文件.

我在最后一点遇到麻烦 - 将a转换TarArchiveInputStream成a FileOutputStream.

奇怪的是,它在这条线上打破了:

FileOutputStream fout = new FileOutputStream(destPath);

destPath 是一个具有Canonical路径的文件:C:\ Documents and Settings\Administrator\My Documents\JavaWorkspace\BackupUtility\untarred\Test\subdir\testinsub.txt

出错:

Exception in thread "main" java.io.IOException: The system cannot find the path specified

知道它可能是什么？为什么它无法找到路径？

我正在附上下面的整个方法(其中大部分是从这里解除的).

private void untar(File dest) throws IOException {
    dest.mkdir();
    TarArchiveEntry tarEntry = tarIn.getNextTarEntry();
    // tarIn is a TarArchiveInputStream
    while (tarEntry != null) {// create a file with the same name as the tarEntry
        File destPath = new File(dest.toString() + System.getProperty("file.separator") …

在proguard.cfg中排除父包后,如何包含某些包:

例如:

-keep com.myapp.**{*; }

我想要proguard来混淆com.myapp.data.**{*; }

任何人都可以指出(或提供？)一些很好的,明确的如何在Win32中实现滚动的例子？显然,谷歌提出了很多东西,但大多数例子对我来说似乎太简单或太复杂,无法确保他们能够证明正确的做事方式.我在当前项目中使用LispWorks CAPI(跨平台Common Lisp GUI库),在Windows上我有一个难以弄清楚的与滚动相关的错误; 基本上我想通过Win32 API直接做一些测试,看看我是否可以对这种情况有所了解.

非常感谢,克里斯托弗

一直在和Proguard一起战斗,并在官方的Proguard网站和StackOverflow上尝试了很多示例和解决方案.

我有一个需要混淆的大型项目,它有许多引用的库项目和Jars.

我从2个libs,com.google.common和twitter4j收到来自proguard的725个警告.

如果我添加以下内容,我很乐意让项目编译:

-dontwarn com.google.common.**

-dontwarn twitter4j.**

然而,应用程序在打开时立即崩溃,所以这似乎只是一种隐藏问题的方式,而不是修复它.

proguard-project.txt位于项目根目录中,其配置位于project.properties文件中,如下所示.

proguard.config=${sdk.dir}/tools/proguard/proguard-android.txt:proguard-project.txt

这是我的proguard-project.txt文件

在使用符号加密然后解密和验证时，我在验证时不断在流中获取未知对象。消息完整性检查已通过，但是当我尝试在解密后的下一行进行验证时，出现上述错误。
